Abstract: A sharps collector (10) comprising a container for holding, storing, and disposing syringes. The sharps collector includes a disposable receptacle (12) and a decorative cover (14). The receptacle preferably has two elongate apertures (40) and chutes (54) associated wit each aperture (40) and chutes (54) associated with each aperture (40). The chutes (54) are designed to guide syringes into the receptacle (12) once the syringes pass through an aperture (40). The chutes (54) also obstruct syringes which are already contained in the receptacle (12) from protruding or re-emerging out of the receptacle (12). The decorative cover (14) is reusable and fits over and attaches to the receptacle (12). When the cover (14) is attached to the receptacle (12), it conceals the apertures (40) and chutes (54) of the receptacle (12). The cover (14) includes an elongate aperture through which a shuttle is accessed. The shuttle (16) directs syringes to the concealed apertures (40) and chutes (54) of the receptacle (12). The syringes to be disposed are placed in the shuttle (16) and the shuttle (12) is manually shifted such that a syringe is pushed towards an aperture (40) and chute (54). The syringe then falls through the aperture (40), is guided by the chute (54), and ultimately falls into the receptacle (12) and is contained within the collector (10). The cover (14) can be detached from a receptacle (12) when that receptacle (12) is ready to be discarded. <IMAGE>

Abstract: A system is provided for regenerating reducing agents used in ancillary chemical or electrochemical processes such as restoring solderability of electronic components. The system includes a cathode, an anode, and an electrolyte system that is separated by a semipermeable ionic barrier into a catholyte and an anolyte. The catholyte includes the reduced member of a redox couple, which can be regenerated electrochemically. The redox couple of the electrolyte system is charged like a battery and discharged during the ancillary process. Regeneration of the reduced member of the redox couple is accomplished at the cathode. The cathode comprises an electrode having a high hydrogen overvoltage so that sufficiently negative potentials can be attained while minimizing hydrogen evolution. Chemical balance is maintained by the semipermeable ionic barrier, which permits proton migration from the anolyte to the catholyte but acts as a barrier against diffusion and migration of cations from the catholyte to the anolyte. Ideally, the anodic reaction is breakdown of water to form oxygen, which is vented, and protons that migrate across the ionic barrier to the catholyte replacing protons consumed in the ancillary process. The overall reaction in a system for restoring solderability of electronic components is reduction of metallic oxide to metal and release of oxygen, with no net chemical change in the composition of the regeneration system.
